Driving on Blockhouse Bay Road a few days ago, I saw a symbol that I didn't understand on signs for the motorway. It is an upright light orange triangle with a white border on a green background. It is not a temporary warning sign, they are tilted squares with a black border, with a darker orange background. It is not a detour symbol, they are usually white with a black border, and the signs have been there for at least 3 years.

Here is a crop from Google maps, the image dated June 2021:

Its marking the dangerous goods route for vehicles that cannot use the Waterview Tunnel,

"All prohibited vehicles must use the detour route which is clearly sign-posted with a red 16 or 20 shield or orange triangle. For the official detour route please see this map."

Thee's another one here heading south just after the rail bridge

Could it be "slow moving vehicles ahead"?

I think it is the generic tunnel detour route, as opposed to a specific dangerous goods route. However, the advice is for dangerous goods to follow this detour route.

If the tunnel is closed for maintenance or you're driving a vehicle which is not allowed to use the tunnels, you can use this route. Simply follow the orange triangle or the SH16 / SH20 red shields on the signs along way.
